Abstract: 본 발명의 변위 확대 기구를 사용한 초정밀 가공용 장행정 공구대는 압전 액츄에이터(20)와, 상기 압전 액츄에이터(20)의 작동에 의해 직선이동되는 이송부(24)와, 상기 이송부(24)의 직선이동시 상기 압전 액츄에이터(20)와 이송부(24)를 연결하도록 상기 압전 액츄에이터(20)와 이송부(24)의 연결부에 형성된 탄성 힌지(26)와, 상기 압전 액츄에이터(20)와 이송부(24) 사이에 피봇점(32)을 중심으로 각각 회전가능하게 개재된 한쌍의 레버(30)와, 상기 이송부(24)에 예압을 가하도록 설치되는 한쌍의 스프링(40)을 포함한다.
본 발명에 의하면, 지렛대의 원리가 적용된 탄성 힌지의 변위 확대 기구가 사용됨에 따라 압전 액츄에이터의 기본 변위를 증폭시키게 되며, 지렛대의 회전축과 초기 변위 확대 부위가 한 평면에 위치함으로서, 변위의 확대 과정에서 발생가능한 변위 손실이 최소화되며, 병렬 형태의 탄성 힌지 가이드에 의해 공구의 직선 이송이 가능한 효과를 가진다.-

Abstract: A long stroke instrument for super precision machining using a displacement enlarging tool is provided to minimize the loss of displacement in the course of enlarging a process by locating an axis of rotation of a lever and an initial displacement enlarging part on one plane. A long stroke instrument for super precision machining using a displacement enlarging tool comprises a piezoelectric actuator(20), a movable part moving straightforward by the activation of the piezoelectric actuator; an elastic hinge(26) formed in a joining part in order to connect the piezoelectric actuator and the movable part when the movable part moves straightforward; a pair of levers(30) interposed between the piezoelectric actuator and the movable part in order to rotate around the pivot point; and a pair of springs applying pre-load to the movable part.
